Abstract: in view of the underground water pump room traditional workers inspection labor intensity, inspection time long, high cost, test results are not accurate, this paper to the underground coal pump room intelligent inspection robot system, using modular and lightweight design ideas, on the basis of the analysis of water pump room inspection content and requirements, put forward a crawler water pump room intelligent inspection robot system, real-time acquisition underground water pump room site is parameter information, instead of workers to complete the underground water pump room inspection task. The hardware system design of the intelligent inspection robot was completed, the control system program was written with the modular thought, and the inspection track program was written, which can be independently inspected according to the set track. A in Shanxi coal mine for site commissioning and commissioning show that the underground water pump room intelligent inspection robot system can replace 4~6 workers inspection, reduce the labor intensity, inspection cycle from a day to 3 times in a single day, inspection efficiency greatly improved, the robot ontology mobile positioning error 5 cm, can accurately obtain equipment running abnormal characteristics and alarm.
